lorri watch takes forever and I can't run it in verbose mode

[korayal]

Describe the bug
lorri watch or lorri daemon takes ~20 minutes to complete a project (using 100% of the cpu) that has all it's dependencies available in /nix/store. When I run nix-shell on the same folder, I can drop into the shell right away, but for lorri it keeps taking forever. I get the same result when I shut down lorri daemon after it completes a project build event, re-run lorri daemon and wait for it to build the same project.

To Reproduce
Steps to reproduce the behavior:

1. run lorri daemon --verbose
2. trigger direnv on a folder
3. wait for it to be completed

Expected behavior
It should be outputting debug logging and it shouldn't take that long for a project to be completed.
